How we test products

Our mission is to take the guesswork out of finding the perfect sleep products.

We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product. 

Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.

To learn more about our testing process, check out our methodology page.

If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.

Even though the Emma mattress and the Simba mattress are high-quality choices, they are very different in composition.

Simba Hybrid mattress
The Simba mattress combines pocket springs with foam.

The Simba mattress is a hybrid model that combines conical mini pocket springs with multiple layers of foam, while the Emma Original is largely a memory foam mattress.


Interestingly, Simba used to be a pocket sprung memory foam mattress. 🤔

This previous version featured a layer of memory foam and a layer of latex foam, making it more similar to the Emma Original.

Simba Sleep has replaced the older version of the Simba mattress with one that's more breathable. 💨

The mattresses are now suitable for different people.

We'll go through the specific composition and features of each mattress in more detail in the next section.

Emma vs Simba: Which mattress is best suited to you?

The Simba Hybrid and Emma Original mattresses are both very comfortable, but they're suited to very different types of people.

The mattresses have different levels of firmness and different compositions that highlight unique features.

Both, though, are excellent choices if you're looking for mattresses that are more environmentally friendly. 🌱


The Emma Original and the Simba Hybrid are free from harmful chemicals and toxins.

They're also both fire-retardant & adhere to UK fire regulation BS7177. 🔥

Simba Hybrid: superior support and breathability

The Simba Hybrid is slightly softer and offers better temperature regulation than the Emma Original.

We've rated it at 5.5 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.

Simba Hybrid firmness scale

The Simba mattress offers excellent support, even pressure distribution, and optimal spinal alignment no matter which sleeping position you prefer.

It is particularly comfortable if you sleep on your back. 😴

This mattress also offers excellent edge support, meaning that you can use the full width of the mattress without ever feeling like you're falling off the sides.


It's also easy to move around on, making it suitable for restless sleepers. 🕺

Finally, the Simba Hybrid has been designed with breathability in mind, making it an excellent choice for heavier sweaters.

Choose the Simba Hybrid if you:

  • Are a light- or average-weight sleeper.
  • Sleep on your side or back.
  • Prefer mattresses with medium firmness.
  • Are a warm sleeper or sweat a little more heavily.
  • Are a restless sleeper.
  • Like the hybrid design.
  • Want good edge support.

The Simba mattress cover is also removable and washable. 😔


You can also clean the grey base fabric with a soft, damp cloth, but we would strongly recommend using a waterproof mattress protector to safeguard your mattress.

We've linked to a few of our favourite mattress protectors at the bottom of this section.

Emma Original: soft, body-hugging comfort

The Emma mattress is slightly firmer than the Simba Hybrid.

We've rated it as 6 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.

Emma Original firmness scale

This makes it an excellent choice for lighter- or average-weight people, particularly if they like to sleep on their side.

When sleeping on your side, your hips and shoulders need to sink in more deeply to keep your spine optimally aligned. 📐


The Emma mattress allows for this.

It is also often recommended as an orthopaedic mattress.

The one drawback of this body-hugging comfort is that moving around on the Emma mattress becomes a little more cumbersome. 💃

So, we wouldn't recommend memory foam mattresses like the Emma Original for restless sleepers.

Choose the Emma Original if you:

  • Want a mattress with body-hugging support and orthopaedic properties.
  • Are of lighter or medium build.
  • Sleep on your side.
  • Prefer soft mattresses.
  • Want a no-fuss mattress with a removable and machine-washable cover.

The Emma Original will be less suitable if you're of a larger build, a pure back or stomach sleeper, a heavier sweater, or a restless sleeper.

Even though the Emma Original has a machine-washable cover, we'd recommend further safeguarding your mattress with a mattress protector.

Mattress protectors safeguard against moisture, spills, and bacteria, and elongate the lifespan of your mattress.

What about other Emma vs Simba mattress comparisons?

Even though the Emma Original and the Simba Hybrid are the flagship products, both brands also have a few other mattresses available.

The other Simba mattresses (Simba Hybrid Essential, Simba Hybrid Pro and the Simba Hybrid Luxe) are very similar in composition to the Simba mattress. 🙌

But, these are more premium mattresses with a greater height and better temperature regulation.

This excludes the Simba Essential, of course, which is a low-height "budget" mattress.


simba hybrid essential
The Simba Hybrid Essential is a low-height mattress.

The other Emma mattresses, in contrast, are remarkably different.

While the Emma Original is a pure memory foam mattress, the Emma Hybrid and the Emma Premium are both hybrid mattresses.

These are more similar in composition to the Simba Hybrid.

Simba Hybrid vs Emma Hybrid

The Emma Hybrid and the Simba Hybrid are both hybrid mattresses that feature mini pocket springs.

The key difference between these two is that the Emma Hybrid has an additional layer of memory foam. In contrast, the Simba Hybrid has an additional layer of open-cell Simbatex foam.


The Simbatex foam will be better suited to more restless sleepers. 🏃‍♂️

The Simba Hybrid also offers better breathability than the Emma Hybrid, making it more suited to heavier sweaters.


Simba Hybrid vs Emma Premium

While the Emma Premium is also a hybrid mattress, it uses full-size pocket springs, not mini pocket springs. 🌀

The Simba Hybrid, Simba Hybrid Pro, and the Simba Hybrid Luxe all use mini pocket springs.

You'll get far more stability, support, and breathability from the Emma Premium mattress than you would from the Simba mattress.


Simba hybrid luxe
The Simba Hybrid Luxe is a thick and luxurious mattress.

The Simba Hybrid Pro and Simba Hybrid Luxe are both thicker mattresses, though. ⭐️

Depth of Emma Premium and Simba premium mattresses:

  • The Emma Premium has a height of 25 cm (10 inches)
  • The Simba Hybrid Pro has a height of 28 cm (11 inches)
  • The Simba Hybrid Luxe has a height of 31 cm (12 inches)

If you're looking for a bed that looks far more luxurious and is easier to get in and out of, then the Simba Hybrid Pro and the Simba Hybrid Luxe are better choices.

Which mattress is better, the Emma Original or the Simba Hybrid?

As you'll have hopefully discovered in our Emma vs Simba review, both the Emma Original and the Simba Hybrid are high-quality mattresses that offer comfort and support for the best night's sleep.

One isn't necessarily better than the other, but they are suitable for very different types of people.

The Simba Hybrid is best suited to:

  • People who like hybrid mattresses.
  • Light- and average-weight sleepers.
  • People who sleep on their side or back.
  • People who like a medium-firm feel.
  • People who prefer more edge support.
  • Heavy sweaters.
  • Restless sleepers.


The Emma Original is best suited to:

  • People of lighter or medium build.
  • Side sleepers.
  • People who prefer soft mattresses.
  • People who require an orthopaedic mattress that will offer body-hugging comfort and relieve pressure points.


Regardless of your choice, you'll get to enjoy a risk-free trial period, giving you the chance to try out the mattress in the comfort of your own home.

After all, testing a mattress is the only way to figure out if it's perfect for you. 🥳

And if you're not 100% convinced, you can return the mattress for a full refund.

Frequently asked questions

  • Should you choose Emma, Eve, or Simba mattresses?

    If you're torn between the Emma Original, Eve mattress, and the Simba Hybrid, then you'll have to choose one of three very high-quality options.

    We would recommend you read our full Emma vs Simba review here, as well as our Emma vs Eve review and Eve vs Simba review.

    These will give you a lot more detail in helping you decide.

    But here a quick overview:

    • The Emma Original is a memory foam mattress with good orthopaedic properties that's well suited to lighter-weight side sleepers.
    • The Eve Original is a memory foam mattress better suited to a wider range of sleeping positions.
    • The Simba Hybrid is a hybrid mattress that's good for restless sleepers, heavier sweaters, and those requiring a little more support.

    All three mattresses come with a risk-free trial period, so you can return them for a full refund if you're not 100% satisfied.

  • Should you choose Emma, Simba, or Nectar mattresses?

    While both the Emma Original and the Nectar are memory foam mattresses, the Nectar can be regarded as more of a pure memory foam mattress.

    In terms of composition, the Nectar is an entirely different mattress to the Simba Hybrid.

    The Nectar is also much firmer than the Emma Original or the Simba Hybrid.

    It is particularly well-suited to sleepers of average weight who like a firmer feel.

    Our suggestion:

    • Choose the Emma Original if you're a lighter-weight side sleeper and want an orthopaedic mattress.
    • Choose the Simba Hybrid if you need breathability and enjoy a cooler feel when sleeping.
    • Choose the Nectar if you're of average weight and like the memory foam feel.

    The Emma Original and Simba Hybrid come with a 200-day trial period, while the Nectar comes with a 365-night trial.

    This means that you can try any of these mattresses for an elongated period of time to see if they're right for you. 

    And if they're not, you can return them for a full refund.

    45% OFF NECTAR

  • Can I buy the Emma mattress and the Simba mattress on Amazon?

    Both the Simba Hybrid mattress and the Emma mattress are available on Amazon in the UK.

    Amazon in the UK is better than other stockists or independent retailers.

    You generally get the same trial period and delivery conditions as when you buy from the mattress brands directly.

    Occasionally, you'll even get the same discounts! 

    This isn't the case with Simba but is generally true with Emma mattresses.
